Coal centrifuge is a kind of dehydration equipment that uses the centrifugal force generated by mechanical rotation to realize the separation of solid-liquid mixture. The slime passes through the material inlet and passes through the distribution cone to make the space between the screen basket and the spiral discharge rotor.
Under the action of centrifugal force, water and small particles (centrifugal liquid) pass through the material layer, pass through the screen, flow into the water collection tank on the upper part of the machine base along the upper cover, and then are discharged from the machine through the drain pipes arranged on both sides of the machine base. Outside: The coal particles are kept inside the screen basket. Because there is a speed difference between the spiral discharge rotor and the screen basket, the spiral discharge rotor scrapes the coal particles from the screen and pushes them to the bottom of the screen basket, thereby reducing The dehydrated slime (dehydrated product) is discharged into the collecting hopper under the machine, and this dehydration process is continuously carried out.
The linear vibrating screen uses the vibration motor as the source of vibration power, so that the material is thrown up on the screen while moving forward in a straight line. The material enters the inlet of the screening machine evenly from the feeder, and generates data through the multi-layer screen. The oversieve and undersieve of various specifications are discharged from their respective outlets. It has low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust spillage, automatic discharge, and is more suitable for assembly line operations.
The linear vibrating screen is driven by dual vibration exciters. When the two vibration exciters are synchronized and rotated in opposite directions, the excitation force generated by the eccentric block cancels each other in the direction parallel to the axis of the motor, and in the direction perpendicular to the axis of the motor. Stacking is a resultant force, so the trajectory of the screen machine is a straight line. The two motor shafts have an inclination angle relative to the screen surface. Under the combined force of the exciting force and the material’s self-gravity, the materials are thrown up and jump forward on the screen surface for linear motion, so as to achieve the purpose of screening and grading the materials. It can be used to realize automated operations in the assembly line. It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance, and a fully enclosed structure without dust spillage. The maximum sieving mesh is 400 meshes, which can screen out 7 kinds of materials with different particle sizes.

Compared with the traditional sieve of the same specification, the banana vibrating screen developed by our company has a larger processing capacity. Its processing capacity per unit area is 1.5~2 times that of the traditional one. It is a kind of vibrating screen with higher cost performance.
Basic knowledge of nucleic acid
Nucleic acid is divided into deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), among which RNA can be divided into ribosomal RNA (rRNA), messenger RNA (mRNA) and transfer RNA (tRNA) according to different functions.
DNA is mainly concentrated in the nucleus, mitochondria and chloroplasts, while RNA is mainly distributed in the cytoplasm.
In nucleic acids, purine bases and pyrimidine bases have conjugated double bonds, so nucleic acids have ultraviolet absorption characteristics. The ultraviolet absorption of DNA sodium salt is around 260nm, and its absorbance is represented by A260. It is in the absorption trough at 230nm, so ultraviolet spectroscopy can be used. The photometer is used for quantitative and qualitative determination of nucleic acids.
Nucleic acid is an amphoteric electrolyte, which is equivalent to a polyacid. A neutral or alkaline buffer can be used to dissociate nucleic acid into anions, which are placed in an electric field and move towards the anode. This is the principle of electrophoresis.
Principles and requirements of nucleic acid extraction and purification
1. Ensure the integrity of the primary structure of nucleic acid
2. Eliminate pollution from other molecules (such as eliminating RNA interference when extracting DNA)
3. There should be no organic solvents and high concentrations of metal ions that can inhibit enzymes in nucleic acid samples
4. Minimize macromolecular substances such as protein, polysaccharides and lipids as much as possible
Nucleic acid extraction and purification method
1. Phenol/chloroform extraction method
Invented in 1956, after phenol/chloroform treatment of cell crushing liquid or tissue homogenate, nucleic acid components mainly composed of DNA are dissolved in the aqueous phase, and lipids in the organic phase, and proteins are located between the two phases.
2. Alcohol precipitation method
Ethanol can eliminate the hydration layer of nucleic acid and expose the negatively charged phosphate groups. Positively charged ions such as NA﹢ can combine with the phosphate groups to form a precipitate.
3. Chromatography column method
The special silicon matrix adsorption material can specifically adsorb DNA, and RNA and protein can pass through smoothly, and then use high salt and low pH to bind nucleic acid, and low salt and high pH to elute to separate and purify nucleic acid.
4. Thermal cracking alkali method
Alkaline extraction mainly uses the topological difference between covalently closed circular plasmids and linear chromatin to separate them. Under alkaline conditions, denatured proteins are soluble.
5. Boiling cracking method
The DNA solution is heated to use the characteristics of linear DNA molecules to separate the DNA fragments from the precipitate formed by denatured proteins and cell debris by centrifugation.
6. Nano magnetic bead method
After the surface of superparamagnetic nanoparticles is improved and surface modified by nanotechnology, superparamagnetic silicon oxide nanomagnetic beads are prepared. The magnetic beads can specifically recognize and efficiently bind with nucleic acid molecules on the microscopic interface. Using the superparamagnetism of silica nanospheres, under the action of Chaotropic salts (guanidine hydrochloride, guanidine isothiocyanate, etc.) and an external magnetic field, DNA and RNA are separated from samples such as blood, animal tissues, food, pathogenic microorganisms, etc. .
7. Other methods
In addition to the above-mentioned commonly used methods, there are multiple methods such as ultrasound, repeated freezing and thawing, enzymatic hydrolysis, and hypotonic lysis.
8. Types of nucleic acid extraction
1. Total RNA extraction
Of the total RNA, 75-85% is rRNA (mainly 28S-26S/23S and 18S/16S rRNA), and the rest consists of mRNA and small RNA with different molecular weights and nucleotide sequences such as tRNA, 5S rRNA, 5.8S rRNA, miRNA, siRNA, small nuclear RNA (small nuclear RNA, snRNA) and nucleolar small molecule RNA (small nuceolar RNA, snoRNA) and other components.
2. miRNA extraction
MicroRNAs (miRNAs) are small, highly conserved RNA molecules, such as small interfering RNAs (siRNAs), which regulate the expression of their homologous mRNA molecules by base pairing with them to prevent expression through various mechanisms. They have become a key regulatory agency for development, cell proliferation, differentiation and cell cycle.
3. Genomic DNA extraction
For gene structure and function research and genetic diagnosis, it is usually required that the length of the obtained fragment is not less than 100-200 kb. In the DNA extraction process, various factors that cause DNA fragmentation and degradation should be avoided as much as possible to ensure the integrity of the DNA and lay the foundation for subsequent experiments.
4. Plasmid extraction
The plasmid extraction method is to remove RNA, separate the plasmid from the bacterial genomic DNA, and remove proteins and other impurities to obtain a relatively pure plasmid.
The magnetic bead nucleic acid extraction kit designed and produced by Luoyang Aisen Biotechnology Co., Ltd. is packaged in a carton, containing a deep well plate and a stirring sleeve. The deep well plate contains magnetic beads, lysate, washing solution, binding solution and eluent, in addition to individually packaged proteinase K.
